I need a 4 foot fixture for a 55gal that i will set up at the end of July. I have experience with the Sunlight Supply TEK, so I am looking for a used 4 foot TEK light. But, I can't seem to get my hands on one. 
As I am trying to keep costs down, I am wondering if anyone has experience with lights from 
http://www.fishneedit.com/, specifically the T5HO. 
Basically, I would love another TEK, but I am looking for advice and opinions now.  
Thanks
